At Linucon 2004 Eric Raymond gave a speech on the basic principles of the Unix philosophy. They are the same principles as described in the "Basics of the Unix Philosophy" chapter of Raymond's book "The Art of Unix Programming". Since the book is available online, I put a link to each rule so you could compare what's said in the book with what was said in the speech. He dwelled a little longer on each rule and gave more examples than he does in this chapter of the book. At the end of the speech he answered questions, some more, some less related to Unix philosophy. He also ranted on XML (after admitting not having an opinion about it) and expressed his opinion on Hurd.
